Anxiety, depression, impulsivity and substance misuse in violent and non-violent adolescent boys in detention in China

The present investigation aims to identify the factors which differentiate violent from non-violent juvenile offenders, with a particular emphasis on the association between internalizing psychiatric morbidity (i.e. anxiety and depression), impulsivity, substance misuse, and violence. A total of 323 incarcerated male juvenile offenders from one of three Youth Detention Centers (YDCs) in China were recruited between August 2007 and November 2008. Interviews were conducted by trained psychiatrists using the Barratt Impulsivity Scale (BIS-11), the Screen for Child Anxiety Related Emotional Disorders (SCARED), and the Birleson Depression Self-Rating Scale (DSRS) to assess impulsivity, anxiety and depression, respectively. The Schedule for Affective Disorder and Schizophrenia for School-Age Children Present and Lifetime (K-SADS-PL) was also used to assess psychiatric diagnoses. Violent offenders had significantly higher BIS-11 total scores, and attention and nonplanning subscale scores (p<0.05). In the multiple logistic regression model, substance use disorders (SUD) and BIS-11 total scores independently predicted violence. Prison-based treatment services designed to reduce impulsivity and substance misuse in juvenile detention facilities should be prioritized.

Australia's response to sexualised or sexually abusive behaviours in children and young people.

Responding to children and young people with sexualised or sexual offending behaviours presents significant challenges across the allied health, child protection, education and juvenile justice sectors. This report maps the specialised therapeutic services designed to effect positive behavioural change and thus divert young people with sexualised behaviours from the juvenile justice system. Accurate numbers on children with sexualised or sexual offending behaviours are difficult to determine. There are several factors contributing to this gap in understanding. These include entrenched ideals about children as inherently innocent, widespread ignorance about developmental sexuality, and the tendency of both young people and parents to deny or minimise incidents when they do occur.

In Australia, data on children with sexualised behaviours are not collected uniformly and nondisclosure contributes to what might be large numbers of offences going undetected. Mandatory reporting requirements apply where children display sexualised behaviours and are thought to be at risk of harm. Yet a general lack of knowledge as to what constitutes appropriate behaviour means that many may respond inappropriately to incidents of sexualised behaviours. This context of confusion, denial and non-disclosure creates a hidden population of children that continues to be at risk. Attention to redressing the contexts for non-disclosure is urgently required to ensure that children in need are provided with specialised therapeutic care.

This report presents qualitative data from interviews with specialised clinicians as well as submissions from service providers in both community and youth justice settings. In mapping the availability of therapeutic services, this report highlights a number of geographic and demographic gaps in service provision, including difficulties with eligibility criteria, referral pathways, funding arrangements and specialised workforce development. There are multiple challenges facing the tertiary services sector, yet the comprehensive provision of specialised services is just one part of the response required. This study emphasises the need for effective primary and secondary prevention to effect a reduction in the numbers of young people requiring counselling in the future. Consistent with the public health model, this report prioritises professional and community education strategies that would ultimately necessitate fewer tertiary services for young people and fewer places in juvenile detention centres.

Comparison of brood size and juvenile weight between a blue strain and normal-coloured strains of the Australian freshwater crayfish Cherax Destructor Clark (Decapoda: Parastacidae)

A blue strain of the yabby Cherax destructor albidus was compared to two normal-coloured strains of C. d. destructor and C. d. albidus for brood size and juvenile weight. Reproductive performance of the blue strain was found to be significantly poorer than the two normal-coloured strains. Similarly, the weight of newly independent juveniles was also found to be significantly lower for the blue strain. No differences were detected between the two normal-coloured strains in either reproductive performance or size of newly independent juveniles. The phenotypic differences between the blue strain and normal-coloured strains are most likely genetic. However, further studies are needed to investigate whether these differences are due to pleiotropy or inbreeding effects.

Performance of juvenile Murray cod, Maccullochella peelii peelii (Mitchell), fed with diets of different protein to energy ratio

The results of a 56-day experiment on juvenile Murray cod, Maccullochella peelii peelii, an Australian native fish with a high aquaculture potential, of mean weight 14.9 ± 0.04 g, fed with five experimental diets, one a series of 40% protein content and lipid levels of 10, 17 and 24% (P40L10, P40L17 and P40L24), and another of 50% protein and 17 and 24% (P50L17 and P50L24) lipid are presented. The specific growth rate (SGR) (% day−1) of fish maintained on different diets ranged from 1.18 to 1.41, and was not significantly different between dietary treatments, except P40L10 and the rest. However, there was a general tendency for SGR to increase with increasing dietary lipid content at both protein levels. The food conversion ratio (FCR) for the 40% protein series diets were poorer compared with those of the 50% protein diets, and the best FCR of 1.14 was observed with the P50L17 diet. The protein efficiency ratio (PER), however, was better in fish reared on low protein diets. The net protein utilization (NPU) also did not differ significantly (P > 0.05) in relation to dietary treatment. As in the case of PER the highest NPU was observed in Murray cod reared on diet P40L24 and the lowest in fish fed with diet P50L24. The carcass lipid content reflected that of the diets, when significant increases in the lipid content was observed in relation to dietary lipid content at both protein levels. However, body muscle lipid content did not increase with increasing dietary lipid content, and was significantly lower than in the whole body. The fatty acids found in highest concentration amongst the saturates, monoenes and polyunsaturates (PUFAs) were 16 : 0, 18 : 1n-9 and 22 : 6n-3, respectively, and each of these accounted for more than 60% of each of the group's total. The muscle fatty acid content was affected by the dietary lipid content; for example the total amount (in μg mg−1 lipid) of monoenes ranged from 72 ± 5.1 (P40L10) to 112 ± 10 (P40L24) and 112 ± 2.8 (P50L17) to 132 ± 11.8 (P50L24) and the n-6 series fatty acids increased with increasing dietary lipid content, although not always significant. Most notably, 18 : 2n-6 increased with the dietary lipid level in both series of diets.

Preliminary study on the use of synthetic substrate for juvenile stage production of the yabby, Cherax destructor (Clark) (Decapoda: Parastacidae)

Juvenile Cherax destructor (commonly called the yabby) (mean weight 48.3 mg) were cultured intensively (stocking density 360/m²) under controlled conditions for 48 days. The animals were provided with a combination of food (high protein pellets and/or natural feed organisms attached to a conditioned synthetic substrate) and refuge. Fastest growth and highest yield was recorded when both pellets and the conditioned synthetic material were provided. Although the yabbies sheltered in the synthetic substrate, it did not increase survival. Juvenile yabbies (< 200 mg) were able to graze on small organisms attached to the synthetic material but this ability appeared to decline as the yabbies grew to a larger size. The use of artificial substrates in the intensive nursery phase production of juvenile freshwater crayfish is discussed.

Home truths about home detention

The Victorian Parliament has recently introduced a Bill which implements home detention as a sentencing option. Home detention is an intuitively appealing reform. The logic behind the proposal seems obvious. Prisons are expensive to run. There are too many offenders in prison. So let's take the cost out of prison by turning the homes of offenders into prisons: classic, user-pays, cost-shifting economics. The level of superficial appeal of the argument in favour of home detention is matched only by the depth of the fallacies underpinning some of the fundamental premises. The most basic of which is the assumption that offenders who are candidates for the new sanction should be in detention (of any kind) in the first place. Further, the narrow objective of reducing imprisonment is misguided. It should not be elevated to a cardinal sentencing objective?otherwise total success could be achieved by simply opening the prison gates. There are also other concerns about the appropriateness of home detention. The degree of pain it inflicts in many cases is questionable and it may also violate the principle that punishment should not be inflicted on the innocent. After examining the arguments for and against home detention, this article suggests the approach that should be adopted to achieve enlightened and meaningful sentencing reform.

Voluntarism, salvation, and rescue : British juvenile migration to Australia and Canada, 1890-1939

This article explores the relationships between governments and selected voluntary organisations involved in British migration to Australia and Canada from the 1890s to the Second World War. Prior to the Great War, there was considerable ill feeling by Dominion governments, especially Australian, towards philanthropic organisations, which appeared to undermine official immigration schemes through their attempts to reclaim and transplant the unwanted. Although voluntary associations were later subsidised by the British government and came under the group nomination schemes of the 1922 Empire Settlement Act, they were still viewed with suspicion. Organisations focusing on 'salvation', 'redemption' and 'rescue' in their migration work, however, provide us with an alternative ideology to the idea of building up 'fit populations' in the Dominions, where the notion of 'fitness' was perceived in a number of ways, not least in terms of class.

Commonwealth legislative power and "non punitive" detention: a constitutional roadmap

In 2004 The High Court handed down a number of decisions concerning detention imposed for purposes allegedly unrelated to punishment. This paper outlines the way the Federal Constitution restricts (and also facilitates) the imposition of "non punitive detention" by our governments. Such laws (as passed by the Federal Legislature) are constitutionally valid provided they can be characterised as falling within a legislative head of power under  section 51 off he Constitution. The power to detain for non punitive purposes can be reposed by the Legislature in the either the Executive or Judicial arms of government. Detention by the Executive is non punitive (and therefore does not offend the separation of powers) even though it involves a deprivation of liberty, provided it is imposed for “legitimate non punitive purposes”.  Legitimacy is in turn determined by reference to the section 51 heads of power. Detention for non punitive purposes by the judicial arm of government is constitutionally valid provided that (i) a “judicial process ” is adopted and (ii) (arguably) there is some link (albeit tenuous) with a previous finding of criminal guilt. The continuing existence of the “constitutional immunity ”from being detained by other than judicial order identified by the High Court in its 1992 decision in Lim v Minister for Immigration is called into question.

Preventative detention and the right of personal liberty and security under the International Covenant on Civil and Political Rights, 1966

Preventive detention enables a person to be deprived of liberty, by executive determination, for the purposes of safeguarding national security or public order without that person being charged or brought to trial. This paper examines Article 9(1) of the International Covenant on Civil and Political Rights, 1966 to assess whether preventive detention is prohibited by the phrase 'arbitrary arrest and detention '. To analyse this Article, this paper uses a textual and structural analysis of the Article, as well as reference to the travaux preparatoires and case law of the Human Rights Committee. This paper argues that preventive detention is not explicitly prohibited by Article 9(1) ofthe International Covenant on Civil and Political Rights 1966. If preventive detention is 'arbitrary', within the wide interpretation of that term as argued in this paper, it will be a permissible deprivation of personal liberty under Article 9(1) of the International Covenant on Civil and Political Rights, 1966. Preventive detention will, however, always be considered 'arbitrary' if sajeguards for those arrested and detained are not complied with, in particular the right to judicial review of the lawfulness of detention.

Preventive detention and the right to personal liberty and security under Article 5 ECHR

'Preventive detention' refers to detention by executive order as a  precautionary measure based on predicted criminal conduct. Detention is without criminal charge or trial as detention is based on the prediction of a future offence. This paper examines Article 5 of the European Convention for the Protection of Human Rights and Fundamental Freedoms ('ECHR'), in particular Article 5(1)(c) and Article 5(3). To explore this issue, this paper conducts a textual analysis of Article 5 and examines both the travaux preacuteparatoires of the ECHR, as well as jurisprudence of the European Court of Human Rights. This article argues that preventive detention is specifically provided for under the second ground of detention in Article 5(1)(c). A person in preventive detention, however, must be brought promptly before judicial authority under Article 5(3).

Growth performance, feed efficiency and fatty acid composition of juvenile Murray cod, Maccullochella peelii peelii, fed graded levels of canola and linseed oil

n two independent experiments, the effects of dietary inclusion of canola and linseed oil were evaluated in juvenile Murray cod (Maccullochella peelii peelii, Mitchell) over a 112-day period. In each experiment, fish received one of five semi-purified diets in which the dietary fish oil was replaced with canola oil (Experiment A) or linseed oil (Experiment B) in graded increments of 25% (0–100%). Murray cod receiving the graded canola and linseed oil diets ranged in final weight from 112.7 ± 7.6 to 73.8 ± 9.9 g and 93.9 ± 3.6 to 74.6 ± 2.2 g, respectively, and exhibited a negative trend in growth as the inclusion level increased. The fatty acid composition of the fillet and liver were modified extensively to reflect the fatty acid composition of the respective diets. Levels of oleic acid (18:1 n-9) and linoleic acid (18:2 n-6) increased with each level of canola oil inclusion while levels of α-linolenic acid (18:3 n-3) increased with each level of linseed oil inclusion. The concentration of n-3 highly unsaturated fatty acids in the fillet and liver decreased as the amount of vegetable oil in the diets increased. It is shown that the replacement of fish oil with vegetable oils in low fish meal diets for Murray cod is possible to a limited extent. Moreover, this study reaffirms the suggestion for the need to conduct ingredient substitution studies for longer periods and where possible to base the conclusions on regression analysis in addition to anova.

Dispersal and recruitment of juvenile Red-capped Robins, Petroica goodenovii

Data on the dispersal and recruitment of juvenile birds following fledging are largely unreported for Australian birds. In this study, we investigated the short-distance dispersal of a sample of colour-banded, juvenile Red-capped Robins, Petroica goodenovii, in Terrick Terrick National Park, Victoria, Australia. Of 67 colour-banded juvenile birds that successfully reached independence during the 2000–01 breeding season, eight were recruited into the study area or adjacent areas for the following breeding season. A ninth bird was resighted in Gunbower State Forest, 36 km from where it was banded. This is the furthest recorded dispersal movement of a Red-capped Robin. Of 59 colour-banded juvenile birds that reached independence during the 2001–02 season, four remained within the study area for the remainder of the breeding season, but these birds were not present in the study area during the following breeding season. Juvenile birds that successfully reached independence and dispersed were heavier as nestlings, when controlled for age and date, than birds that disappeared (assumed dead) before reaching independence. Estimates of Red-capped Robin abundances within Terrick Terrick National Park were greater than those of nearby eucalypt woodlands, suggesting that the White Cypress-pine, Callitris glaucophylla, woodlands within the park offer good-quality habitat for Red-capped Robins and may be saturated with breeding territories. Thus, juveniles may be forced to establish breeding territories far from their natal territories. These results are discussed in relation to avenues for further research on juvenile dispersal in Australian birds and their conservation implications.
